What is the use of power grid?

The power grid transmits electricity from where it is generated to where it is used. A good site is:

The power grid distributes electricity from generation sources (power plants) to end users (homes and businesses). The grid also helps regulate the flow of electricity to where it is needed, and prevents upsets in power supply.

Hope this helps,

Hi Raju,

A power grid is the network of electrical wires that covers an entire country or often a continent, and whose purpose is to distribute electrical power that is generated by power generating plants, to everyone in the country (or even the continent in many cases) who uses this power. The power grid also allows "redundancy"; that is, if one electrical generation station has a failure, other generating stations can help to send more power into the grid, to make up for the power loss.

Without an electrical grid, there would be no way to get the electrical power from power generating stations, to everyone who uses it.


Bob Wilson

Power grids take electrical power from various sources and deliver the electrical to other consumers of electrical power. This makes efficient use of electrical power. The details of how this occurs is not simple.
